Systems and methods for detecting and decoding 4-state barcodes with extreme bar dilation are disclosed. The method is implemented in a computing device and includes: separating an extracted image of a barcode into a top half and a bottom half; estimating bar positions and then sampling heights of the top and bottom images at each position; using adjacent bar height differences to determine the top and bottom of the tracker portion for each bar position; removing the tracker contribution to the top and bottom heights at each bar position; sending the resulting sequence of bars with ascender and descender information to a decoder for decoding processes.

The present disclosure is directed to systems and methods for strike through detection and, more particularly, to systems and methods for detecting a strike through in an address block of a mailpiece. The method is implemented in a computing device and includes: generating edges of lines within a text block identified through optical character recognition processes; locating text lines within the text block; characterizing the edges within the text lines and outside of the text lines; and grouping identified edges of the characterized edges outside of the text lines into co-linear groups.

Systems and methods for strike through detection

The present disclosure is directed to systems and methods for warp and shear detection and correction and, more particularly, to systems and methods for detecting and correcting shear and warp in an address block of a mailpiece. The method is implemented in a computing device and includes: locating a barcode which is spatially consistent with a block of text; obtaining barcode bar data from the barcode which correlates to a difference in spatial orientation of one or more bars of the barcode with respect to a best fit line through the barcode; and replacing the block of text with a non-distorted block of text which can be read by optical character recognition processes, based on the barcode bar data.

Systems and methods for reducing the likelihood of false positive decodes within a set of barcodes are disclosed. The method can be implemented in a computing device, which includes: providing a list of barcode configurations that meet damage tolerance criteria; reducing, if possible, each configuration list to barcode configurations that have a compatible configuration pair between sets; and comparing all possible combinations of barcode type configurations to find at least one set of configurations that are resistant to false positives decodes between barcode types during decoding processes.

Methods and system for automatic identification of repeating patterns of slanted stripe features (marks) on an item.

Methods and systems for detection of repeating patterns of features

Method and systems for early detection of potentially hazardous material associated with the collection of mail or other objects. In an embodiment of the method of this invention, image characteristics for an image of an item being examined are obtained. A predetermined profile is then retrieved from a profile database. The image characteristics for the image of the item are compared to the image characteristics present in the predetermined profile. If the image characteristics present in the predetermined profile substantially match the image characteristics for the image of the item, the item is identified for special processing. If the image characteristics present in the predetermined profile do not substantially match the image characteristics for the image of the item, another predetermined profile is retrieved and compared to the image characteristics for the image of the item. A system that implements the method of this invention includes a transport sub-system and a computing sub-system.

Mail image profiling and handwriting matching

The present invention is directed to a bar code symbol having stored thereon a data structure. The data structure includes a plurality of module elements. Each module element is configured as a bar symbol or a space symbol. The data structure includes a start character containing predetermined number of module elements. The predetermined number of module elements is configured in a predetermined pattern of bars and spaces. A data portion is configured to encode a single numerical value. The data portion has one termination data character and 0 to N Continuation characters, wherein N is an integer value. The data structure also includes a stop character.
